1 HNMR和13CNMR光譜鑒定為氧化苦參堿、氧化槐定堿、苦參堿、槐定堿和 lehannine。結(jié)論 首次從苦豆子種子中分得 lehm annine。;Object To study the alkaloid constituents in the seed of Sophora alopecuroides L. and isolation of lehmannine by transhydrogenation of sophocarbine to matrine present in the mixture. Methods Various processes of exchange, ion exchange and column chromatograph with very similar physical and chemical properties was successfully separated by transhydrogenation. Results 5 alkaloids were obtained and identified by elementary analysis, IR, MS, 1HNMR and 13CNMR as oxymatrine, oxysophoridine, matrine, sophoridine and lehmannine (12, 13-dehydromatrine). Conclusion Lehmannine was isolated from the seed of S. alopecuroides for the first time."/>
